irq_forced_thread

Name:Interrupts which are not explicitly requested as threaded* interrupts rely on the implicit bh/preempt disable of the hard irq* context. So we need to disable bh here to avoid deadlocks and other* side effects.

Proto:static irqreturn_t irq_forced_thread_fn(struct irq_desc *desc, struct irqaction *action)

Type:irqreturn_t

Parameter:

Type	Parameter	Name
struct irq_desc *	desc
struct irqaction *	action

ret = thread_fn(irq, dev_id)

986

If ret == IRQ_HANDLED Then atomic_inc( & threads_handled)

989

Oneshot interrupts keep the irq line masked until the threaded* handler finished. unmask if the interrupt has not been disabled and* is marked MASKED.
